Room Controller Network Serial Integration

Overview

Third party systems are able to send serial commands to Room Controller Network lighting control

panels. These serial commands are sent using the TCP/IP protocol over the building LAN to an Ethernet

Interface Module (EIM) or ControlKeeper M (CKM) panel. The EIM or CKM will then forward the serial

commands onto the lighting control system RS-485 network.

Serial integration can be used to allow AV, BMS or other systems to send commands to the Room

Controller Network panels and set dimmer levels, relay states or trigger remote commands.

Command Types Supported Commands

Manual Commands Relay (On/Off)

Dimmer Commands Dimmers (0 – 100%)

Remote Commands Remote (On/Off)

Disclaimer

Connection

The Room Controller Network system connects to the Building LAN via an Ethernet Interface Module

(EIM). The system requesting serial integration must also connect to the Building LAN and be able to

make a TCP connection to the EIM. Consult your local IT expert to insure proper IP routing can be

achieved.

The Ethernet Interface Module must be properly configured and installed. Consult the EIM installation

instructions shipped with the unit or via the web site.

The Ethernet Interface Module (EIM)

may be connected to any ControlKeeper panel in the system using the RS-232 cable

included (Material #: 52-018703-00)

3rd Party Serial Integration

Building LAN/

Network Switch

Figure 1: Room Controller Network Serial Integration Connection


Packet Format

Packet: [Flag] [Length] [Physical To Address] [Physical From Address] [To/From Address] [Type Flag]

[DATA] [LRC]

Flag: (1 byte) All data information coming from any external device must be preceded by an AA

hexadecimal (170 decimal). If the incoming information is not preceded by the AA hex then the

information will be ignored by the Room Controller Network.

Length: (1 byte) This byte informs the LCP receiving the message of the number of bytes

following this byte up to and including the LRC.

Physical TO Address: (1 byte) This byte is the address of the LCP (in hexadecimal) that this

message is for. All LCP’s have hardware which allows them to reside at a certain "logical"

address. This address range is from 1 to 254. Only the LCP at this specific address will listen to

the message. Please note that address 0 and 255 should not be used.

Physical FROM Address: (1 byte) The byte for the Physical FROM Address field is always zero

(00).

Logical TO/FROM Address: (1 byte) Transmissions entering the panel RS232 port will always be

zero (00) for this field.

Type Flag: (1 byte) The type flag defines the exact function of the data being transmitted. The

supported type flags are described below.

DATA: (N bytes) The variable-length field associated with each Command field is detailed in

section 5 ”Command Types Flag”.

LRC: The (1 byte) Linear Redundancy Check (LRC) is an XOR of all the bytes in the frame

transmission including the flag character, up to but not including the LRC byte. This byte is used

to check for valid transmissions of data to the Lighting Control Panel. The calculation for the LRC

is shown below:

lrc = 0;

for ( index = 0; index < message length; index = index + 1 )

{

lrc = lrc XOR data[ index ];

}


Type Flags

The command Type Flag defines the type of protocol packet to be sent to the LCP. The type number is

in hexadecimal.

Type 02 - Remote Command

In a Room Controller Network, remote commands are used to send preset commands to the Room

Controller. Remotes can trigger allow groupings of relays within the controller or controllers to respond

to a single command. The status field returned will include some indication of whether or not the

controller could perform the requested function with 1=OK and 0=not done.

Function Type Remote Name Remote State ACK Status

Remote Command 02 8 Byte Hex Name 02 = OFF

03 = ON

Remote Acknowledge 02 8 Byte Hex Name 02 = OFF

03 = ON

1 = OK

0 = No remote by this name

Remote Command Examples

Below are some examples of the use of remote commands. The examples are listed in hexadecimal.

“FF” in the Physical To Address field is a Global and will be sent to all lighting control panels on the

network. When “FF” is in the Physical To Address field no Acknowledgement is sent from the panels. If

a Remote Command is sent to a specific panel address a Remote Acknowledgement is sent.

Remote

Name

ON Command OFF Command

TIM3 AA 0E FF 00 00 02 [54 49 4D 33 20 20 20 20] 03 39 AA 0E FF 00 00 02 [54 49 4D 33 20 20 20 20] 02 38

NOTE: The LRC of each transmission will be different based on the panel address and data information changes.

See the calculating LRC section for examples.

Type Flag Description

Type 02 Remote Command

Type 03 Manual Command

Type 0E Dimmer Command


Type 03 - Manual Command

This is used to command a single digital output (relay) on the network to an ON or OFF state. This

command is sent to the relay name.

Function Type Relay Name Relay State ACK Status

Relay Command 03 8 Byte ASCII Hex Name 01 = ON

02 = OFF

Relay Acknowledge 03 8 Byte ASCII Hex Name 01 = ON

02 = OFF

1 = OK

0 = No relay by this name

Manual Command Examples

Below is an example of a manual relay commands to Room Controller Network panel address #1. The

example is listed in hexadecimal.

Relay # ON Command OFF Command

Relay 2 AA 03 01 00 00 03 [52 65 6C 61 79 20 32 20] 01 D6 AA 03 01 00 00 03 [52 65 6C 61 79 20 32 20] 02 D7

Type 0E - Dimmer Commands

This is used to command a single dimmer level within a Room Controller on the network to a % light

level (0-100%). This command is sent to the dimmer name.
